Title: Dispositivo de compensação de pressão para um recipiente de duas partes
Inventor: HOCHRAINER DIETER
IPC: B67D7/60
Filed: 1999-11-08
Abstract: Patente de Invenção: "DISPOSITIVO DE COMPENSAçãO DE PRESSãO PARA UM RECIPIENTE DE DUAS PARTES". Recipientes de duas partes são usados para fluidos médicos, os quais consistem em um recipiente interno e um recipiente externo que é impenetrável a difusão. O recipiente interno fecha quando o fluido é removido. Para as finalidades de compensação de pressão entre o espaço gasoso, é necessário um dispositivo de compensação de pressão disposto entre os recipientes interno e externo e o ambiente do recipiente de duas partes, por meio do qual, ao mesmo tempo, a perda do fluido através da difusão do recipiente interno que pode ser fechado é mantida tão baixa quanto possível. Para essa finalidade, pelo menos um canal é usado, o qual comunica o espaço intermediário cheio com gás com o ambiente do recipiente de duas partes. A constante de tempo para compensação de um diferencial de pressão de uns poucos milibars está dentro da região de muito poucas horas. Isso é obtido pela seleção do comprimento do canal e seção transversal do canal. O, pelo menos um, canal pode ser produzido individualmente ou uma pluralidade de canais pode estar presente na forma de poros em um material sinterizado com poro aberto ou em uma membrana permeável. O dispositivo de compensação de pressão permite a armazenagem do recipiente de duas partes por muitos anos, e o uso por muitas semanas à medida que o fluido está sendo removido em uma maneira em porção. Durante esses períodos, a quantidade de fluido no recipiente interno, ou a sua concentração, muda substancialmente menos do que com o uso de um recipiente de duas partes conhecido.

Title: Device to aid nappy changing
Inventor: HASKINS MARK JOHN
IPC: A47D5/00
Filed: 2000-04-25
Abstract: A device to aid nappy changing consisting of three parts the main two sections of which 1 lie one over the other beneath the infant's head and shoulders. Vertical extensions 4 of these sections rise on either side of the infant's torso keeping the infant's arms at approximately 90{ to it. A panel 10 is attached between the vertical extensions, above the infant's torso, bridging the gap between them and preventing the infant's hands and arms moving downward. The vertical extensions have inner edges 5 at an angle to them. These help the device remain in place and stop the edges digging in to the torso. The distance between the vertical extensions can be adjusted to allow the device to be used on infants of different sizes. The main sections of the device are flexible to allow it to be used with changing mats with raised sides. They may slide relative to each other to adjust the spacing between the extensions 4 are held in place by elastic bands 2.

Title: Scrolling display apparatus
Inventor: BUTLER EDWARD MAURICE PIERCE
IPC: G09F11/29
Filed: 2001-03-22
Abstract: A display apparatus, for example a light box 10, has a web 16 windable between a pair of parallel spaced rollers 12, 14. The web 16 carries display posters and is releasably attached to one roller 12. The other roller 14 is spring-loaded (92, Fig 4) to rotatably bias the roller 14 against movement of the web winding onto the one roller 12.

Title: A hydraulically operated directional control valve
Inventor: REINELT WERNER
IPC: F16K37/00
Filed: 2001-09-20
Abstract: A hydraulically operated directional control valve 10, for hydraulic cylinders of hydraulic support mechanisms in underground mining, comprises a valve piston 16 and a control piston 18 screw threaded together at 17 and reciprocable in a valve seat carrier 15 and a control piston guide 19, respectively. A control pressure introduced via ST lifts the pistons against bias of spring 21 to move valve cone 20 away from seat 22 and partially open high pressure connection P to a load connection A and to return flow connection T via gaps 28 and 33. Return flow connection T is closed when the forward end 42 of the control piston engages sealing cone 43, at which time connection P is fully opened. The interval between fully opening P and closing T can be adjusted. The valve thus achieves an opening and closing characteristic with negative overlapping and so provides gentle switching processes, so that switching impacts with high pressure peaks do not arise.
